Chris Brown debuted his new rap song at a Hollywood party for Diddy on Tuesday (February 26). Brown was reportedly accompanied by Rihanna for the evening and delivered the expletive-laced lyrics to the delight of Supperclub attendees.

The impromptu performance, which was captured on video by SkeeTV, shows Brown in a sea of partygoers as he drops his lines with gusto.

“Every n**** in the hood see the same h***/ With the same friends all they do is change clothes/…If you f****** for your rent, you a lame h**”

It’s unclear if this song will appear on his forthcoming album but Brown’s next set is already underway.
